Roof Ventilation: Why It Matters

Home Improvement

Many homeowners in Sydney probably know that their roofs and attics are well-ventilated, but don’t necessarily understand why ventilating them matters. Ventilation, as you well know, is the flow of air in an environment. In your home, you would increase this airflow by opening your doors and windows and often, installing exhaust fans, or opting for a skylight installation Sydney service.

But, ventilation in your attic and roofs are essential, too. It extends the life of your roof, reduces energy costs, and lowers indoor temperatures. These benefits weren’t well-documented in the past. But, today, its value is evident in the many roofs that sport vents and incorporate styles that are good for ventilation.

With all these said, let’s take a more in-depth look at how ventilation works and why it matters more than ever.

How Roof Ventilation Works

A roof ventilation system works by providing consistent airflow through the roof space. In the process, it helps remove overheated air and moisture from the roof and reduce the effects of these elements on the interior and exterior of your home.

Several types of vents are often used in different locations to provide good roof space ventilation. Some of them include the following:

  • Static Vents – the horizontal openings, often vent-covered holes in the roof that promote good airflow.
  • Ridge Vents – the vents that run along the peak of a roof. As hot air rises, they exit out of the ridge vent, while the cool air is pulled in from below.
  • Gable vents – the vents that are installed in the ends of the attic and are recommended for use in conjunction with other types of vents.

The Benefits of Proper Roof Ventilation

The correct design and installation of roof ventilation systems are critical to guarantee the balance of intake and exhaust of air under the roof and eaves.

It prevents roof damage. The hot weather can heat your roof and as a result, increase the temperature in the attic. When exposed to such excessive heat, your roof sheathing can warp and distort while your shingles can curl up and prematurely age.

Having well-ventilated roofs and attics mean preventing heat buildup and the damages associated with it.

It reduces energy cost. As if roof damages are not costly enough, the heat that builds up in your roofs and attics can also radiate down the interiors of your home, making it more costly to keep your living spaces cool.

Maintaining proper ventilation in these areas is necessary to reduce the burden on your HVAC systems. The logic here is simple: an air conditioner that runs less generates lower energy bills.

It prevents moisture buildup – The extreme heat is not the only issue here. In colder months, moisture can get trapped in your attic where it will condense—whether that be from rain, snow, or steam from your shower or dryer. This condensation will eventually drip back and penetrate your insulation, potentially leading to mould and mildew growth.

What’s worse is that this moisture can also form on your eaves, soffits, and other parts of your roof. When that happens, they can cause further water damage that can be costly to repair.

If you have concerns about the ventilation in your roof and attic, it’s a smart move to contact a licensed roofing contractor in Sydney who can inspect and assess whether there’s enough ventilation. If more is needed, they can help outline the necessary steps you should take and discuss your options to improve your existing roof ventilation system.
